Stargaze prioritizes UX and UI to offer the most seamless user experience. Stargaze is 100% carbon neutral and requires zero gas. It is powered by CosmWasm and $STARS. Stargaze offers a fully decentralized NFT marketplace and exemplifies high levels of security, transparency, and flexibility. All chain code is open-source. \n
\n\n**Challenge #1:**\n
\n\nCreate governance adjustable entry incentives and exit tax for NFT transfers. \n
\nStargaze aims to make a comfortable home for NFTs to live on-chain. In order to facilitate this, we would like to build a mechanism that pays an incentive for NFTs that come to Stargaze from other chains. Inversely, Stargaze would like an adjustable tax for NFTs that transfer to another chain. This is very similar to a tariff mechanism in trade between two different countries. \n
\n\nA diagram can be seen here: [https://github.com/public-awesome/ics721/issues/52](https://github.com/public-awesome/ics721/issues/52)\n
\n\n*For this task you will collaborate with @0xekez (Twitter)*\n\n**Challenge #2:**\n
\n\nStargaze aims to integrate with Gravity Bridge in order to enable NFT transfers from Ethereum. In order to do this, we will need the following steps to be completed: \n
\n\n(1) Install sdk.nft 0.46 on Gravity Bridge testnet. Gravity Bridge will be using sdk.nft and therefore needs the upgrade. The testnet branch can be found here: [https://github.com/Gravity-Bridge/Gravity-Bridge/tree/christianborst/sdk-upgrade-v0.46](https://github.com/Gravity-Bridge/Gravity-Bridge/tree/christianborst/sdk-upgrade-v0.46)\n
\n\n(2) Install sdk.nft based ics721 version into Gravity Bridge. \n
\n\n(3) Update Gravity Bridge orchestrator in the following way: \n- Listen to the NFT transfer into gravity contract event on Ethereum\n- Construct an ics721 packet\n- Publish ICS721 packet to the chain\n
\n\n(4) Test an NFT transfer from Ethereum -> Gravity Bridge -> Stargaze\n
\n\n*Note for this challenge, you will be collaborating with @synchronetic (Twitter)*\n
\n\n**[New] Challenge #3:**\n
\n\nStargaze aims to make a seamless experience for it's users through an aesthetically pleasing and easy to understand UI. ICS721 is a complex protocol that is not easy for the average user to use through the command line. \n\nIn this challenge you will design a UI for ICS721 to transfer NFTs between Stargaze and other chains. The UI should have the minimum number of buttons and options. Bonus points for designing the look and feel as similar to the main Stargaze website as possible. \n\n**Docs**\n

Stargaze prioritizes UX and UI to offer the most seamless user experience. Stargaze is 100% carbon neutral and requires zero gas. It is powered by CosmWasm and $STARS. Stargaze offers a fully decentralized NFT marketplace and exemplifies high levels of security, transparency, and flexibility. All chain code is open-source. \n
\n\n**Challenge #1:**\n
\n\nCreate governance adjustable entry incentives and exit tax for NFT transfers. \n
\nStargaze aims to make a comfortable home for NFTs to live on-chain. In order to facilitate this, we would like to build a mechanism that pays an incentive for NFTs that come to Stargaze from other chains. Inversely, Stargaze would like an adjustable tax for NFTs that transfer to another chain. This is very similar to a tariff mechanism in trade between two different countries. \n
\n\nA diagram can be seen here: [https://github.com/public-awesome/ics721/issues/52](https://github.com/public-awesome/ics721/issues/52)\n
\n\n*For this task you will collaborate with @0xekez (Twitter)*\n\n**Challenge #2:**\n
\n\nStargaze aims to integrate with Gravity Bridge in order to enable NFT transfers from Ethereum. In order to do this, we will need the following steps to be completed: \n
\n\n(1) Install sdk.nft 0.46 on Gravity Bridge testnet. Gravity Bridge will be using sdk.nft and therefore needs the upgrade. The testnet branch can be found here: [https://github.com/Gravity-Bridge/Gravity-Bridge/tree/christianborst/sdk-upgrade-v0.46](https://github.com/Gravity-Bridge/Gravity-Bridge/tree/christianborst/sdk-upgrade-v0.46)\n
\n\n(2) Install sdk.nft based ics721 version into Gravity Bridge. \n
\n\n(3) Update Gravity Bridge orchestrator in the following way: \n- Listen to the NFT transfer into gravity contract event on Ethereum\n- Construct an ics721 packet\n- Publish ICS721 packet to the chain\n
\n\n(4) Test an NFT transfer from Ethereum -> Gravity Bridge -> Stargaze\n
